KERN 347-036 Hook Calibration Weight — OIML M1, 5 g
A KERN 347-036 hook weight for calibration of balances and hanging scales, designed for traceable small-mass verifications in workshops and laboratories
- OIML Class M1 precision, 1.6 mg tolerance
- 5 g nominal weight for fine calibrations
- Finely turned stainless steel construction
- Hook form for easy suspension on balances
Reliable accuracy for routine calibrations
The OIML Class M1 specification ensures that deviations remain within 1.6 mg, which makes this weight suitable for the verification and adjustment of high-precision balances and hanging scales used in quality control and laboratory environments. The declared 5 g nominal mass provides a clearly defined calibration point for low-range checks; class conformity supports comparability of results and helps to document measurement uncertainty in traceability chains. Operators and technicians benefit from consistent, reproducible readings that reduce retesting and save time in scheduled calibration routines.
Robust material and design for lasting stability
Manufactured from finely turned stainless steel, the component resists corrosion and wear, which maintains mass stability over repeated use and handling. The compact cylinder form with dimensions 8×22 mm delivers a small footprint while the hook design permits secure suspension beneath balance pans or on test fixtures, eliminating the need for improvised attachments. The machining finish minimises surface imperfection and contamination risk, contributing to long-term measurement integrity and reducing drift between verifications.
Practical compatibility and handling advantages
As a single calibration weight within the OIML M1 product group, this hook weight is intended for straightforward integration into calibration sets and routine maintenance schedules. Its shape and nominal value make it particularly useful for testing sensitivity and linearity at the low end of a balance’s range. The item is traceable to the manufacturer KERN under SKU 347-036, allowing documentation in quality records and audit trails. Storage on a soft, lint-free surface and handling with tweezers or gloves preserves the surface condition and helps retain specified tolerance during its service life.
For precise small-mass calibrations request the KERN 347-036 from Metav Werkzeuge — our specialists in Emmerich provide product information and availability and can advise on integration into calibration procedures.

Take advantage of a compact, KERN-specified storage solution that protects individual calibration weights and keeps them organised for routine use; the combination of robust plastic construction, compatibility with 1 g–5 g knob/compact weights and straightforward handling ensures reliable daily workflow — order directly via Metav Werkzeuge or consult our team for product matching. Plastic case 347-030-400 — for individual calibration weights, 1 g–5 g, classes F1–M3 (KERN) The Plastic case 347-030-400 is a compact storage and transport solution for individual calibration weights, designed to keep knob/compact weights organised and protected in laboratories, workshops and service environments. Compact plastic case for individual weights Fits knob/compact weights 1 g–5 g Suitable for calibration classes F1–M3 Durable, lightweight storage solution Protects accuracy by preventing contamination and wear The case offers a secure place to store calibration weights so that surface contamination and handling damage are minimised, which in turn preserves measurement accuracy over time. By keeping knob and compact weights separated and secured, the storage solution reduces the need for frequent recalibration and helps maintain compliance with routine test intervals. This protective function is particularly relevant when handling sensitive classes such as F1–M3, where surface condition has a direct effect on measurement results. Lightweight plastic design for easy handling and transport Constructed from plastic, the case is both lightweight and durable, making movement between benches or job sites straightforward without adding significant bulk. Weighing approximately 0.02 kg, it supports convenient handling while providing a firm housing for individual pieces. The material choice balances protection with portability, offering a practical alternative to heavier metal cases where the primary requirement is safe short-term storage rather than long-term extreme environmental protection. Organises calibration workflows for faster selection and traceability A dedicated case reduces search times and streamlines the selection of the correct nominal weight during routine checks, improving operational efficiency in workshops and service departments. Clear organisation contributes to faster test cycles and less downtime, which in aggregate supports productivity goals. Where traceability is required, consistent storage in a defined case helps operators maintain an orderly inventory and reduces human error during weigh-ins and calibrations. Compatible with industry practice and a recognisable brand Designed for use with knob/compact weights in the 1 g–5 g range and suitable for classes F1–M3, the case aligns with common metrology practice and complements existing weight sets from established manufacturers. The KERN designation signals compatibility with professional weighing equipment; origin details indicate manufacturing standards consistent with European metrology supplies. As a simple yet effective accessory, the case supports routine maintenance of weights without introducing complex handling procedures.
